Fig. 33 is a side view of one of the pull ,ba-rs, its slide and theratchet driven thereby. Fig. 34 is a side View of another one of thepull bars and the `means' operated thereby. The machine has a revolvingneedle carrier 1, the needles being indicated at 2.

There is a group of main yarn guide tingers at each side of the machine,these being for diderent colors of kinds of yarn. The fingers 3 of eachgroup are pivotalfy mounted side by side at 4 in brackets 5 tired tothesinker cam ring 6 which is held against rotation by a stud 7 extending'from a bracket. 8, said stud entering a notch in the cam ring.

The main yarn fingers 3 incline downwardly and inwardly from theirpivots towards the axis of the machine and feed the yarn to the needlesthrough mouths 10, 10 of a latch guard ring 11 iXed by screws 12 to thestationary top plate or sinker cam ringy of the machine. These fingersare thrown down into operative position by vertical push rods 13 mountedtoslide in the brackets 5. '.These push rods are operated selectively bya plunger 14 which is positioned under the proper push rod by' theslidably mounted in the bracket 5. The low-V er end of the plunger restsupon a lifter plate' 16 which is of sufficient width to insure contactwith the lower end of the plunger in all positions to which the lattermay be moved by the carrier according to the demands of the patternmechanism, as will be described hereinafter. This lifter plate ispivoted at 17 to the fixed bracket and it has a roller 18 designed to beacted on by a rotary cam member 19, ixed beneath the rotary sinker bed,This cam operates the lifter, at each revolution of the machine, and ifthe plunger 14 has been moved by its carrier 15 to a position under oneof the push rods 13 (there being four in each. group) the rise Vof theouter end of the lifter will elevate the plunger and cause it to push upon the proper rod 13, which, acting on the tail 3of the yarn linger,will throw this down to feeding position. The cam 19 has an incline 19which gives to the roller 18 its downward movement suflicient to lowerthe yarn linger, as just stated, to feeding position. It4 has anadditional rise 19 which gives the yarn finger a slight additionaldownward movement, the result of which tion 3 of the depressed fingerwill throw down a latch plate 20, and as soon as the'finger has reachedits final position the latch plate will rise under the action of itsspring 20 and said operated yarn linger will be retained in its operatedAposition to continue feeding the yarn. The same action, just described,which results in the depression of the latch plate by the movement ofthe operated yarn linger downward to feeding position, will release anyone of the yarn 1ingers of this group, so that this will rise andwithdraw its yarn from work. This rise of Athe released yarn finger'willhe due to the action of the spring 3"* with which each yarn finger isprovided at its pivot. Fig. 1 shows one finger in low or feedingposition held by the latch plate and the upperor released position ofone ofthe fingers is also shown. The release of a finger from feedingposition, above mentioned, is due tov the fact that when the new yarnfinger is thrown down, its projection engages and presses down the outerend of thelatch plate by working against the upper surface of itsupstanding latch portion and carries this low enough to release theprojection 3 of the finger which has been feeding. Any push rod 13 whichmay be operated, can fall down to normal position-as soon as the plunger14 moves away from its lower end, and in this lowered position the pushrods rest upon the upper surface of the plungers carrier block 15. Theplunger itself is under tension of a spring 14 (seated between thewallsof the carrier, which is channel shaped) which forces 1t downwardwhen the lifter plate 16 falls. In its upper position the plunger willbe retained by a detent 14 which is in the form of a leaf spring 14Xhaving the detenta projection 14 to enter a notch 14*L in 'the plunger,i. e., the same notch which the end of spring 14 lies in, but thishappens only when the carrier 15 is at the left hand limit of itsstroke, which is its normal position. The holding up of this plungeralso has the effect of keeping t-he lifter plate 16 up,so that itsroller, which is then down, will not be hit by the rotary cam 19, andtherefore the lifter plate will not fiap up and down idly. Thiscondition is illustrated in the right of Fig. 1. lVhen, however, theplung` er carrier 15 is moved to the right, Fig.y 2, from its vnormalposition of rest at the left ofthe group of push rods, the plunger willmove away from and will no longer be reis that a projec-frelease toinoperative position under the action of tained by the detent, and hencethe spring of the plunger will force it .down and thus tip the lifterplate into position, so that its roller ywill be within the range of thecam 19 and hence will be Ioperated by said cam to swing the outer end ofthe plate upwardly and thus raise the plunger to move the proper yarnfinger into feeding position and the other finger, so that it may riseits spring. This downward movement of thev plunger when the carriermoves to the right is due also to its working against an inoline 14" onthe frame or bracke.

The plunger carrier is moved towards thev right from its left-handposition shown in Fig. 2, by pattern mechanism as follows:

A rod 21 connects the sliding carrier with a lever 22, fixed to a shaft23 mounted in the fixed bracket 8 supported on the fixed base 24 of themachine. This shaft 23 is operated by an arm 23 whose huh is pinnedthereto at 23, the depending end of which arm engages a notch 25 in aslide 25, Figs. 3 and 12, which has pivoted at 26 four pull bars 27.Fig. 3, each of which rest-s upon one of the pins 28 mounted in acarrier har 29. so as 'to slide freely therein, in a substantiallyvertical direction. This .carrier har has movement up and down to theperfo rated pattern strip or jacquard device which in the present caseconsists of an endless sheet of flexible material, as paper 30', passingover a pattern drum 30 referred to more fully hereinafter. The up anddown movement of the pin carrying bar is derived from a cam 31 arrangedcoaxially with the needle cylinder and 4 roller 32 carried hy a slide 33which is guided in the brac et 34, Figs. 2 and 4. This slide hearsagainst an eccentric pin 35 carried by a rocking arm 35 which ispivotally mounted at 36 and is connected with an arm 37 which hasthereon the pin carrying har 29. A spring 38 presses the arm down andthe cam 31 through the connections described, raises the pin carryinghar. fWhen the pin carrying bar is raised it engages the heads of thepins and holds them up. The jacquard strip is perforated and is movedstep by step by the intermittent movement of the drum 30 which has teeth30* engaging marginal openingsin the strip.l Now when the pin carryingbar moves down, any'pin which finds an opening in the paper strip willpass therethrough, but any pin which strikes an im'perforatc. part ofthe strip will be held up, despite the fact, as just stated, that thepin carrying har has lowered. The pin which passes through theperforation in the paper strip will, of course, move down and this willallow the pull har 27, Figs. 2a and 3. which is resting thereon, to`fall also, and this will bring a shoulder 27' on the pull bar'intoadapted to operate against a i position, when weones a `range of anoscillating push plate or bar 39 with the result that,'supposing thepush plate is moving towards the left in Fig. 2, the pull bar 27 whichhas fallen will be pushed leftward and drawing upon the slide 25 willoperate the arm 23' which engages its notch 25', Fig. 3, and turn theshaft 23, thus swinging the arm 22 towards the right and moving theplunger carrier rightward to bring the plunger 14 under the proper pushbar 13 for operatingthe corresponding yarn feed finger into operativethe lifter plate 16 moves upwardly. The train of connections justdescribed will be returned to normal position, as will be hereinafterdescribed. The pull bar which has been operated, as just described, willbe elevated to vnormal position by the rise of the pin carrying bar 29which will elevate the pinfupon which said pull bar rests, and whenraised to this normal position, the said pull bar will be out of rangeof movement of the oscillating bar 39, ready for another action such asjust described, when. the pattern strip calls for it. As before stated,there are four pull bars 27V connected with the one slide 25, and theshoulders 27 of these pull bars are inline with eachother, see Fig. 3,but it will be noticed that the oscillating bar 39 has a series ofshoulders 39 in stepped relation, and consequently at diiierentdistances' from the shoulders 27 of the pull bars 27, so that the slide25 will be moved different distances, according to which one of the fourpull bar is lowered into range of the oscil lating bar 39. rlhe bar 39oscillates always through the same length of arc, it being mounted on aframe 39 pivoted at 39 to the bracket 34, Fig. 2, and it is operated aswill be describedherei'nafter. lf the first one of the'pull bars 27(comiting from the bottom of Fig. 3) is theone lowered, then' theoscillating bar 39 will move this the maximum distance, because itsshoulder 27' stands nearest to the edge of the bar :39;k

This pull bar will therefore cause a full rightward movement of theplunger carrier 15 and the plunger 14 will select the righthand ush bar13 to throw the right-hand yarn nger down to operative position.

the second pull bar 27 is lowered, there will be some lost motion ofthe. oscillating bar 34, so that the plunger carrier 15 will`not bemoved so far to the right as in. the first instance, and consequentlythe plunger 14 will select and operate the second yarn finger (countingfrom the right of the group A, Fig. 3) and so on, as to the otherpullbars 27, each in order being operated to a\lesser degree than thepreceding one, owing lto the stepped formation 39 in relation to theshoulders 27 of the pull bars.

'lihe train' of mechanism just described .B, Fig. 3.l There is a plungercarrier 15a for this side of the machine with rod l21, lever 22a, and ashaft 23a, which latterV is arranged axially in line with the shaftsection 23 above mentioned, and this shaft section 23a is operatedthrough an arm 23b fixed thereon from a slide 25'c1 which is like theslide 25 and has four pull bars 27?' pivoted thereto, to be controlledby certain of the pins 28 and operated severally by the same oscillatingb a'r 39 when the pins find openings in the jacquard strip through whichto pass when the carrier bar 29 is lowered. f A c lit will be noted thatthe fingers of group A4 may be selected in any prescribed order desired,the variations in the order of selec? tion dependingv upon thedisposition of the holes in the jacquard strip, and this is true also ofthe vgroup of fingers B and the order of selection of one group may beentirely different from that of the other group.

" ln other words, the .two 'groups are entirely independent of eachother in the sense that the order of selection of the fingers of onegroup may the other group, though. the selection in respect to the twogroups is derived from. the same source, i. e., the jacquard strip.

The push plate 39 is operated by a spring 40 in one. direction, thisspring being conm nected to the swinging frame. 39, and in the otherdirection the operation is due to a cam 4l operating against a roll 42mounted on a slide 33 which bears against an adjustvary indefinitely inrespect to ing screw 43 carried by the frame. The eccentric pin 35 ofthe lever 35 may be turned for adjustment of its Acontacting relationwith the slide 33 byfa screw driver, the head of this pin being kerfed,and' when adjusted it is held by a set screw 35". The rocking of theframe 39 is utilized for operating the pattern drum step by step, forwhich which the pins 28 pass when an opening in purpose the framecarries a pawl 44 to enj tern drum is substantially like that shown imthe jacquard strip aligns therewith and when the pin is lowered by thebar 29.

ln order to return the carrier slide 15 to normal position at the leftof Fi 2, after being o erated to the right (it eing ob-` served tadvancing shoulder 27', but not the ret-urn shoulder, see Fig. 3) thelever 22 has a at the pull bars 27 have. only ther downward extension22x connected by a rod 46 with an arm 47 on a vertical shaft 48 mountedin the fixed base of the machine and in 'a bearing 49, Fig. 1, and thisshaft carries an arm 50 fixed thereto which is in the path of a rollerl51 on the shaft 52 forming a part of the rotary'take-up mechanism. Thismechanism may be of any suitable type and needs no detailedl descriptionherein, except to say that the revolving frame of -this taken mechanismis shown at 53, and this afi'or s hearings for the shaft 52, one ofwhich is indicated at 54. The shaft is driven by a gear 55 meshing witha circular rack 56 which is supported in xed relation to the frame byarms 57. The shaft 52 carries the clutch 58 which drives the takeuprolls located within the fabric cam 59 and not shown, these rolls beingjonrnai'ed in the revolvin take-up frame 53. rIhe roll 51 travelling aout the axis of the machine will hit the arm 50 and through the :rock

Needle canne.` The machine, bein a two feed type, there are two sets ofneed e cams, shown in Fig. 5, consisting of 'stitch cams a, a', ralslngcams b, b', and fixed cam pieces 0,'0 and d,

diametrically opposite sides of the machine.

Each of the stitch cams is adjustable automatically to knit tight orslack and for thisI l purpose each is screwed to a post 59 which isnormally pressed upwardly by a spring 59 pressing against a` lateralprojection 59 of the post, the spring being seated vin a pocket of thecam block, as in ordinary lowerin the stitch cam against the pressure othis spring, the post is notched` at 59 and a crank member or pin 60enters this notch. This crank pin is journaled in the cam block andon`its outer end it has fixed thereto an arm 60 carrying a screw pin 60to vbear on a controller ring 61, Fig. 1, which on its edge is /formedwith` 'ratchet upper surface is formed with high and low The controllerring is step by a pawl 62 -pivoted ig. 3, which is ivoted at 64 to thebase of the machine an is o erated by a slide 65, guided in the frame oft `e machine and havin connected -pivotally thereto at 66 a pull bar 67which, like the .pull bars before described, is operated leftward, Fig.3, by the push plate 39. This has two shoulders, like the onewhichappears in Fig. 2, so that the push plate 39 will engage oneshoulder to advance the pull moved step b troller ring will allowv thearm 60 and there arev two trick wheels e, e, at t teeth 61 and on itsvneedle cylinder,

bar leftward to turn the controller ring in the arrow y] direction, Fig.3, and when the push plate 39 returns to the right it will engage theother shoulder of the pull bar and return it to normal' position toretract the pawl for a fresh operation. `No detent is required to holdthe controller ring against overthrow, as the action is not rapid andthe friction is su'icient to prevent undue movement. One step movementlwill cause a high part of this controller ring 61 to tip the arm 60 upand this, as indicated at the right of Fig. 5, will cause the Hat face`of the pin 60 to engage the lower shoulder of the cam post 59 and lowerthe stitch cam' for making slackstitches, and when the next stepmovement of the controller ring takes place. according to the demands ofthe pattern mechanism, the low part 61b of the conto lower, thus turningthe crank pin, so that the spring 59 then becomes effective to raise thecam post 59 and allow the stitch cam to assume position forknittingnormally tight.

The control vjust described is exerted at `both feeds simultaneously,because the turningof the controller ring will operate the stitch cams aand a simultaneously, it being understood that there is a crank pin 60and arm 60 at each of the stitch cams. The knitting of the slackcourseis for making, for instance, the necktie. I

The needle raising cams b, b are pressed normally downward by springs 68and they are raised by star wheels or cams 69 which ie in the notches 69of their posts 69, the springs being pocketed in the posts and held inplace by overlying plates 69x fixed to the cam box. The star cams areformed in one piece with the hubs 70 of ratchet wheels 70 which areturned step by step, and at such intervals as are prescribed by thepattern mechanism, by pawls`70.

y'The hubs 70 are journaled in `the cam housing or box 71. The pawls 70are reciprocated once for each revolution of the machine. They arepivotally connected with rocking arms 70x 70, Fig. 2. The arm 70x 72,Figs. -2 and 3, connected with a bell crank 72 pivoted 4to the base ofthe machine and operated by a slide 72 having a pin` 70x engaging anotch in the bell crank lever.

wheels and when these are turned 'toA present their high points beneaththe pawls the latter will be lilted so as toY nnss their ratchets 70 andhence no change in the position of the needle raising cams t, t willtake place, whereas when the ratchet wheels 75 are given their next'step movement, the jflat or low sides of thestar cams will corne underthe pawl bars 70 'and these will lower so and turn the ratchet Wheelsstroke to the right, thus to adjust the nelle raising cams t, bvertically. l

The ratchet wheels75 are turned step by step by pawls 75 pivotallymounted at '751 to slides `76, one 'for each side of the machine, Fig.3, each ol which has a pullbar one of the pins 28 'to be controlledthereby as to its up or down position in respect to the push plate 39which is to beptore described.

Each of these pull bars is advanced and retracted by the push plate 39.

The vertical adjustment oi the needle raising cani` cooperates withtrick wheels in forming the pattern. i It these earns are in their lowerpositions those needles which are not raised to clear their latches willpass these cams in tncking position and tuck stitches will be formed onthese needles, while those needles whose butts engage the seats in thetrick Vwheel will knit, whereas if these raising cams are in theirelevated 'positions all needles will knit, because those which pass bIthe trick wheels in tucking position will e raised bythe cams Z), bf toclear their latches and hence these needles valso will lrnit.

Auxiliary yarn fingere.

Supplemental yarn 'feed lingers are shown at f and g. 'lhese arepivotallymounted in a bracket 77 and are raised and lowered by push rods7? and springs, as at 77". The push rods are operated by star cams at78, Fig. 2, turned by ratchet wheels 78". Pawls 78" turn the ratchetwheels and tliesepawls are worked by levers 79 loosely mounted 'on theshafto23 and operated by slides 79', 7 9, which are operated by the pullbars 80, 80', oi #the pattern mechanism. These fingers are adapted tofeed only those needles which are raised to knitting position by .thetrick wheels.` They will not feed those positions at needles which leavethe trick wheel `in tucking position and hence variations in the patterncan be produced by throwing these lingers into and out of work. Theseauxiliary fingersfwhen lowered to feeding posetion, lie just below theelevated throat l0 of the ring 11, see. diagram Fig. 5, so that theyfeed the yarn over 'the edge of this throat to the needles' which arefully elevated by the trick wheel. This feeding position oi theauxiliary yarn nnger is indicated at f, Fig. 5, and its raised positionat f. The raised position of the other auxiliary yarn linger isindicated atg. Its feeding position is'at the same lowlevel of thefinger at f. This diierence in the ele. vatedpositions of these twolingers is for Vthe purpose of preventing the two yarns from winding ortwisting together-'clear up 'to the yarn fingers' from the center of the`fabric which, if it happened, would prehe y/arns from being fed to theneedles ing a separated position to the two auxiliary yarn fingers whenraised equal to thel distance between f and g, the two auxiliary yarnsare kept apart, so that each may be lowered to feeding positionindividually without interference by the other yarn. The feedingposition oi 'the main yarn fingers is indicated at A and their elevatedA. They lie, when lowered to feeding position, in the throat space 10.The height of the needle wave resulting lfrom the trick wheel seatsl eliitin certain of the needles, `is indicated at c2, an the low wave lineat this point due to the needle butts passing through the cuts e in thetrick wheel periphery, is indicated at e". The wave line passing themain yarn fingers may be low, as indicated at b, if cam b is down, or itmaybe higher up, it cam b is raised, but in either case, the yarn willbe taken by all of the needles at this oint. `The feed Inouth for theother group ofp` lfingers B isy shown at 10.` A 'guide finger o projectsup from the throat l to propand direct the idle yarns 'from thefingers,v

which are raised, towards the machines axis, where these idle yarns aretwisted into a rope or cord form. This action is also assisted by aguard p2 consisting of a wire attached to bar and inclining downwardlyand inwardly. When a yarn nger yarn me l

against the inclined y twisted together,

raised, the point where this yarn is tied guards the yarns will be keptseparate for 'a considerable length thereof extending from the yarnfingers, and thus each may be lowered individually without interferenceby the other yarns, .it being observed that the point where the twistingbegins is below the level of the feeding positions of the yarn fingers.Suppose in Fig. 3 that one of the yarn feed'fingers is lifted out ofwork. The end which is tied into the fabric will travel in the acrossthe interior of the needle cylinder,

'but it will be depressed at its center by sliding down the inclines ofthe plates p and bar p2, and as the rotary movement continues andadditional idle yarn is drawn off, it will twisttogether at y.the centerof the cylinder.

I provide means for counting the number of neckties knit. This consistsof counting mechanism C, Fig. 2, operated by a rod 81, Fig. 2, from alever 82, the lower arm of which is operated by a slide 88, Fig. 3,having a pull bar 84 controlled by the pattern mechanism beforedescribed.

Reverting to the yarn linger selecting mechanism and particularly to theaction of the plunger 14 and the return arm 50, it will be'observed thatthis return arm, when struck by the roller 51, will return the plungercarrier 15 towards the left, Fig. 2, until the plunger 14 gets under thecam inoline 14'. of the bracket. Further movement of the plunger carrierleftward will be due to the rise of the plunger under the action of thelifter plate 16, which will force `the plunger up into contact with thesaid cam incline 14b and thus shift it further leftward. This will havethe effect of throwing the return arm 50 further out, so that it will beentirely outside the path of movement of the rollery 51, so as not to behit idly thereby. This action just described will set the parts at thepattern mechanism in normal position so that at the proper time vtheplunger carrier will be moved towards the right, the plunger 14 will belowered, together with the outer end of the lifting plate 16, so thatvnow be inthe path of cam 19, and the return arm 50 will be set inwardto be struck by the roller 51 when this comes around to restore themechanism partway to normal position, this taking place after thelifting'plate 16 has operated to raise the plunger 14 and vchange theyarn fingers.

i The machine is provided with so-called arrow direction and extend"ingit, a reciprocatory pawl for sinkers or web holders of substantiallyknown form and operation.
